Dr. Judy Hong Jin Joo, MD is published by Glassy Skin Clinic and in her public professional profile as a board-certified dermatologist in Korea (피부과 전문의). A specialist certificate and issuer verification link will be added only after the supporting record is reviewed.

The clinic’s Naver Booking page lists Dr. Judy (주홍진), Dr. Max Young-ho Kim (김영호), Dr. Sophie So-min Kim (김소민) and Dr. Sunny Hong-seon Jang (장홍선). Each doctor has an individual page with source-labelled education and career information.
Which source is used for the doctors’ education and career information?
The clinic’s Korean Naver Booking biographies are the primary source. The English Naver view is linked for access, but obvious machine-translation errors are not repeated. Certificate images and issuer verification remain unpublished until the clinic supplies and reviews supporting records.
Has Dr. Judy published research?
Yes. PubMed lists Dr. Judy as a co-author of a 2024 Marine Drugs laboratory study about extracellular vesicles from Ecklonia cava, phlorotannin and skin-aging models. It was not a human clinical trial and does not establish an individual treatment result.
Is a product or device certificate the same as a medical specialist qualification?
No. A medical specialist qualification, professional membership, training certificate and device or product certificate describe different scopes. Each should name its issuer, holder and status.
Do credentials guarantee a treatment result?
No. Credentials describe professional background; they do not guarantee a particular result. Diagnosis, suitability, risks, alternatives and expected outcomes require an individual consultation.
